Add a usage guide and a runnable example for the section-header level inference shipped in docling-project#3633, docling-project#3688 and docling-project#3984, covering the bookmark, numbering and font-style signals, their precedence, and the generate_parsed_pages requirement of the style fallback.

PR adds that documentation. No library code is touched.

generate_parsed_pagesrequirement of the style fallback.
docs/examples/heading_levels.py(new) — runnable example printing the recovered hierarchy.docs/usage/advanced_options.md,docs/index.md,README.md,mkdocs.yml— pointers and nav.docling/.agents/skills/docling/references/python-sdk.md—heading_hierarchy_optionsadded tothe options table.
Every snippet and level sequence in the guide was executed against this branch.
